One of the early posts in this thread mention EN 590 as being acceptable. EN 590 is the eurpoean biodiesel standard.
Perhaps the US biodiesel "standard", is not acceptable for some reason, or more likely there is no standard formulation that is available widely enough to endorse. Certainly I can understand MB not warranting a sophisticated system such as the Blutek diesel using fuel that Joe Hippie brewed up in a discarded water heater in his barn. -- 1983 300D 1966 230
